JOHN T. EAMES, OF DETROIT, MICHIGAN.

FEED-WATER REGULATOR.

Application filed May 3, 1915.

To all whom it may concern Be it known that I, JOHN T. EAMES, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Feed- Water Regulators, of which the following is a specification, reference being bad therein to the accompanying drawings.

This invention relates to a feed water regulator, and the primary object of my invention is to provide a counter-balanced tilt able water actuated regulator that can be easily and quickly installed in connection with a boiler to automatically control the level of water within the boiler and preclude accidents incident to excessive high and low water levels.

A further object of this invention is to provide a feed water regulator wherein the parts are constructed with a view of reducing the cost of manufacture and at the same time retain the features by which accuracy, safety, durability, and ease of assembling are secured, and with such ends in view, my invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is a front elevation of a feed water regulator, partly in section; Fig. 2 is an enlarged longitudinal sectional view of a combined swivel connection and support for a tiltable controlling member, and Fig. 3 is an enlarged vertical sectional view of a balanced controlling valve.

As illustrating an installation of a feed water regulator, there is illustrated a portion of a wall or boiler setting 1 and a boiler 2 having a steam dome 3.

Suitably supported by the wall 1 is a globular controlling valve 4 having the lower end thereof connected to a water supply pipe 5. The controlling valve 4 has a side connection 6 for a pipe 7 extending to the bottom of the boiler 2, said pipe having a conventional check valve 8 preventing a back flow of water which has entered the boiler 2. The top of the controlling valve 4 has an ordinary stuffing box 9 for a valve stem 10 and this stem, within the valve has a longitudinal port or bypass 11, a packed head 12, and a valve proper 13. The valve proper is adapted to engage a seat 14; in the bottom Specification of Letters Patent.

of the valve body and shut off the supply of water to the boiler I. The packed head 12 has the function of a piston in the upper part of the valve body and with water pressure above said head, the valve stem 10 and its appurtenant parts are counterbalanced.

The wall or boiler setting 1 is provided with a bracket 15 and connected to said bracket by a plug 16 is a T17 connected by a pipe 18 to the side of the boiler 2, said pipe having a conventional valve 19. The 'l" 17 supports a coupling member 20 and swiveled in said coupling member is the flanged end 21 of an elbow 22, said elbow having a trunnion 23 extending into a yoke 2 1 carried by the coupling member 20, said trunnion cooperating with the flanged end 21 of the elbow in supporting said elbowwhereby the same can be tilted relative to the "l" 17. The coupling member 20 supports a stufling box 25 for a gland 26 insuring a non-leakable connection between the coupling member and the elbow 22. Connected to the elbow 2 by a tubular arm or connection 27 is a hollow member 28 in the form of a small tank adapted to receive water from the boiler 2 through the medium of the pipe 18, elbow 22, and tubular arm 27. The hollow member 28 is suspended by a link 29 from a lever 30 fulcrumed upon a bracket 31, carried by the wall 1, said lever having a weight 32 as a counterbalance for the hollow member 28. The outer end of the member 28 is limited in its movement by stops 33 supported from the wall 1 and the normal position of the hollow member 28 is intermediate the stops 33.

The bracket 31 is located above the inner end of the hollow member 28 and provides a smooth convex bearing on which rides the lever 30, said lever having slightly curved cars 41 on the lower edge thereof, against the ends of the bearing, whereby the lever 30, cannot, in its usual operation, become displaced. The ears 4:1 permit of the lever changing its point of fulcrum on the hearing by shifting thereon, such movement being hardly perceptible during the tilting action of the lever. The fact that the lever can change its point of fulcrum prevents the sudden slamming or hammering action, so common is feed water regulators. The form of the bearing also reduces friction to a minimum, making the regulator very sensitive, which is a desideratum in connection with feed water regulators.

The top of the hollow member 28 is connected by a universal joint 34 to a steam pipe 35 connected to the steam dome 3 of the boiler 2, said steam pipe having a conventional valve 36.

The tubular arm 27 of theelbow 22 is provided with a strap or stirrup 37 connected by a rod 38 to an operating lever 39 of the valve 4, said operating lever being connected to the upper end of the valve stem 10 and supported by a bracket l0 forming part of the valve body. The bracket 40 is in the form of a pivoted link that permits of the operating lever 39 being raised and lowered to open and close the valve 4.

As heretofore stated, the normal position of the hollow member 28 is midway between the stops 33 or in a horizontal plane approximating the level of water in the boiler 2. The hollow member 28 being in communication with the boiler 2 contains a small quantity of water which has the same level as the water within the boiler 2 and should the level of water within the boiler 2 become low there is a corresponding low level of water within the hollow member 28, consequently the weight 32 overbalances the hollow member, raising the same, and through the medium of the rod 38 and operatinglever 39 the valve stem 10 is raised to admit water to the bottom of the boiler 2. As the boiler is replenished and the water assumes its normal level the hollow member 28 is gradually restored to normal position by water entering the same.

Should there be an excessive supply of water to the boiler 2, there is an excessive supply of water to the hollow member 28, consequently said member is lowered to the position shown in Fig. 1 and the valve 4 is closed until such time that the water in the v boiler 2 and the hollow member 28 assumes a normal position.

From the foregoing it will be observed that the feed water regulator is automatic in its action and with the hollow member 28 in communication with the steam dome 3 water can readily circulate between the hollow member 28. and the boiler. The regulator requires no attention whatsoever and precludes any possibility of a boiler explosion or other accident due to low or high water in a boiler.

WVhile in the drawing there is illustrated a preferred embodiment of my invention, it is to be understood that the structural elements are susceptible to such changes, as in the size, shape and manner of assemblage, as fall within the scope of the appended claim.

What I claim is In a feed water regulator, the combination with a boiler having a water supply pipe provided with a controlling valve, of a hollow member having one end thereof in communication with said boiler and adapted to receive water therefrom, a flexible pipe connecting said hollow member to the steam space of said boiler, a bracket above the inner end of said hollow member providing a convex smooth bearing, a lever having a changeable point of fulcrum on said bracket, ears on said lever engaging the ends of the bearing of said bracket, a weight at one end of said lever, a link connecting the other end of said lever to said hollow member intermediate the ends thereof whereby said weight and lever maintain the hollow member normally in a horizontal plane with the level of water therein approximately the same as the level of water in said boiler, and means actuated by a movement of said member caused by the raising and lowering the level of water therein adapted to control the operation of said valve.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN T. EAMES.
